Renewed July 21, 1939 Claims. (01. 24264) .I; j

j Our invention relates to improvements in means for supporting heavy web rolls, such, for instance, as the web rolls used in the printing of newspapers,

' For this purposeit is common practice to use a rotary reel adapted to support a plurality" of web rolls which may be brought successively to running position and be spliced to the running web of the press, so as tolinsure. a continuous supply. It is desirable to shift the web supports in unison in order to obtain side register and to 'shift'the supports relatively to eachother in order to mount either fractional width web rolls,-or.

vfull width Web rolls. As the web rolls-qused in newspaper. printing are very heavy, power driven mechanism is employed to shift'the web supports.

Paper roll'stands' or reels of this general type are disclosed inPatents Nos. 1,957,121. and 1,957,122, r issued May 1, 1934. The, reel disclosed in Patentv No. 1,957,121 has two opposed web supports or,

spiderseach provided with a side registerfeed screw driven by its own motor, and the motors maybe operated separately orsimultaneouslyto effect adjustment of the spiders individually or 'inyunison alongthe main shaftof the reel. In

the other of said patents a single feed screw and motor are employed for-both spiders, and-a clutch is provided on each spider for connecting the same to or disconnecting thesame from the feed screw.

An object of the present invention is to provide improvements over both of these previously patented reel constructions; To this end our in-,

vention provides for the use of a single motor for adjusting the spiders and means at a single control station for controlling the operativeconnection of the spiders to the motor, whereby both spiders may be adjusted in unison or either of the spiders-may be adjusted individually with respect to the other.

Another object of our invention is to provide safety means for automatically disconnectingeither or both of spiders from the power drive in case of a jam, was to prevent damage.

- In a preferred form of our invention, two side register feed screws are employed, one for each yspider, with'a. clutch normally connecting-each screw to power, and a controller at one end of the reel for disengaging either of, the clutches.

. A further object of the invention is to provide a clutch controllernormally heldin neutral position with both feed screw clutches engaged, said controller being manuallymovable in one direction from neutral to disengage one of the'clutches and scope of our invention will be set forth in the claims. 1

Our improved reel comprises a, pair'of pedestals l5 and I6 which carry bearings H and I8. 910' Mounted to rotate in these 'b'earings arebearing members l9 and 20 (Figs. 3 and 6) which are fixed to the opposite ends of alreel shaft 2|. The

bearing members l9 and 2t are longitudinally bored to receive a pair of side register screws 23 and 24, respectively, and also a shifter rod 25. The screw 23 is mounted at opposite ends thereof in ball bearings'llfi and 2'! carried by the bearing members liland 20, respectively. The screw 24 is similarlymounted in ball bearings, not shown. p Mounted to slide on the reel shaft 2 lare two hubs 3t and 3!, to which are bolted spiders 32' and 33, respectively. The screws pass through the'sejhubs, screw 23 having threaded engagement with the l spring bears against-a plug 56 screwed into the back the opposite thimble.

Fig. 6, has a yoke 31 clamped thereto which engages a groove 35 in the hub of a control handle 39 keyed to a short shaft 40. This shaft is coaxial with the shaft 2| and its inner end is slidable in a bushing 4I let into'a socketfor'med in the adjacent end of the shaft 2|. The shaft passes through a bushing 42 which is fixed to a housing 43 carried by the pedestal I6. A thread 44 on the shaft cooperates with a groove formed in the bushing 42, so that by swinging the handle 39 from its normal position, shown in fulllines in Fig. '7, to the dotted line position 39a, the shaft will be fedinwardly or to the left, as viewed in Fig. 6, and conversely if the handle is swung to the position 3% the shaftwill be fed outwardly. By reason of the connection between the yoke 37 and handle 39 there will be a corresponding axial adjustment of the shifter rod 25 which, as will be explained hereinafter, controls a pair of clutches adaptedrespectively to connect or disconnect each of the side register screws 23 and M to power.

It is desirable to maintain the handle in its normal position, in which position both of the side register screws are connected to power. To this end, thehandle is provided with a springpressed dowel pin 46 which is adapted to enter an. aperture in the housing 43 to hold the handle in normal upright position.

to unlock the handle-whenever it is desired to swing the handle out of normal position.

It is also desirable to have the handle return automatically to its normal position when released and to this end a pinion 50 is fixed to the outer end of the shaft 40. This pinion meshes with a rack 5! which is slidable in a tubular casing 52 fixed to the housing 43 and disposed transversely to the axis of the shaft 40. A guide screw 53 in thehousing engages a keyway in the rack and prevents rotation of the rack. When in the normal position, illustrated in Fig. 8, each end of the rack abuts a thimble 54 fitted to slide in the casing and partly enclosing a compression spring 55. The opposite end of .each

casing 52. When the handle 39 is swung to the right or left the rack will be moved axially, thereby causing one or the other of the springs to be compressed, and on release of the handle it will be swungback to normal position by the.

compressed spring; In the normal position of the handle each thimb le abuts a shoulder 51 in the casing so that neither thimble may move past normal position when the rack is pressing This obviates the necessity of carefully balancing the springs to hold the handle in normal position. It will be understood, of course, that as soon as the handle reaches normal position the dowel pin will snap into the aperture of the housing 43 and lock the handle in. such normal position.

A cover 58 is provided which is normally fitted over the handle. This cover is connected to the housing-by a pair of pins 59. Either of the pins 2,195,141 1' II was The pin has a knurled projectingend 41 which may be lifted may be withdrawn and the cover may then be swung open on the other pin as a fulcrum. A knob 60 provides a convenient handle for the cover. It willbe observed from aninspection of Fig. 7 that the handle 39 cannot be swung to.

either of the dotted linepositions so; long as the cover is closed. "This arrangement ofparts is purposely provided as an additional safeguard against inadvertent adjustment of one spider without simultaneous adjustment of the other.

The side register screws are arranged to be driven either separately or simultaneously, de-

' pending uponthe-setting of the shifted rod, by

meansofa reversible motor 65. This motor is mounted on a ring 56 bolted to a disk 61 and the latter in turn is bolted to a cup shaped hub 68 of a worm wheellfl, this hub being an integral extension of the bearing member I9. The Worm wheel 10 meshes with a worm II on a shaft 12. The latter is journaled in bearings carried by a bracket 13 bolted .tothe pedestal I5. Keyed to the shaft I2 is a gear 115 which is driven by a pinion I6 fixed upon the armature shaft ;of a reel motor I8. The latter is also mounted on the bracket 13. The motor may be operated to rotate the reel shaft .2I1 throughfthe 'gearing just described, while the motor 65. which is fixed to the worm wheel 10 will rotate bodily with thereel Shaft. I q I Electric power is supplied to motor through pencil electrodes which engagecontactrings 8| mounted on an annulus 82 of. insulating material fixed to the rotarydisk 61. The electrodes 80 are mounted in an'insulatin'g block 83 fixed to a stationary housing 84 carried by the bracket 13. Current is supplied to thefelectrodes through leads, not shown and the circuit to the motor is completed through wires, not shown, which run to the motor from the rings 8|.

The armature of motor 55 hasa pinion 38 fixed thereon which ineshesi witha gear 81 (see Fig. 5). The latter is carried by a double row ball bearing 88 mounted one short shaft 83. This shaft in turn isjmo-untedin'ball bearings 90 and 9| carried respectively in the motor supporting disk 6! and the worm, wheel hub 68.

A clutch plate 92 is secured to the gear 8! and is formed with V shaped radial teeth which mesh with complementary V-shaped teethformed on the adjacent end of a'clutch-sleeve 94 splined upon the shaft 89. The clutch sleeve is normally urged into engagement with the clutch plate by a spring 95 which is compressed'between a flange on the clutch sleeve and a washer 96 on the shaft 89. This washer abuts a pinion 91 "fixed to the shaft 89 whichmeshes with two gears formed in the hub of the clutch gear is engaged by a pair of opposed blocks I05. (Fig. 4). These blocksare carried by yoke arms I06 of the yoke lever 36 which isjou rnaled in suitable bearings fixed to the worm wheel hub 58.

Similarly, a

clutch gear I08 has splined connection with a collar fixed on the end of the screw 24 and is adapted to mesh with an internal gear ring I09 (see Fig. 11) on gear 99. The hub of the clutch gear I08 is formed with a groove engaged v of the shifter rod 25. I gears are normally in half-mesh with the gear ly in one direction or the other.

rings and the screws'23 and 24 are both clutched to their driving gears 98 and 99, respectively, so that should the motor 65 be ,started while the partsare in such normal position both screws will be driven simultaneously and the spiders 32 and 33 will both be fed to the right or left depending upon the direction of rotation of the motor. When the handle 39 is swung out of normal position it will move theshifter rod axial- Such motion will rock the yoke lever, causing one or other of the clutch gears I [I2 and I08 to be disengaged.

from power. The motor 65 will then turn only the screw which is clutched thereto and will ad-' just the position of the spider controlled by said screw while the other spider remains at rest.

It will be recalled that 'the gear train from motor 65 to the two sideregister screws includes a safety clutch 9294 formed with V-shaped teeth. Should a jam occur or an obstacle be encountered which materially hinders movement of the spiders, the V-shaped teethwill cause the clutch member 94 to slideaway from. member 92,

against the pressure-of spring 95,'until the teeth clear each other. The motor can then continue torotat'e-while the spiders arearrested without doing any damage. It will be noted that this. safety clutch is. efiective to prevent damage when either of the spiders is being adjusted independently or when the spiders are being adjusted in unison. j

The reel spiders 32 and 33 are each formed with three arms so as to mount three paper rolls II4 simultaneouslyj Each rollis supported between a pair of chucks. The chucks H5 carried by the arms of spider 32 have limited'axial adjustment under control of a handwheel IIG. These chucks may be of the construction disclosed in copending application Serial No. 737,201, filed July 27, 1934, now Patent No. 2,095,019 of October 5, 1937. The latching chucks II! which are carried by the other spiders 33 are capable of considerable axial adjustment to permit of engaging or disengaging a roll I I4. Despite the extended adjustment provided in each latching chuck the construction is such that the clutch .may be collapsed to a very small axial-dimension.

Details of the latching clutch are shown in Figs. 6 and 9. The clutch comprises an outer sleeve IIB fixed in an armof the spider 33. The

sleeve is formed internally with a right hand thread. A cover plate I29 is fixed to and closes the outer end of the sleeve II 8'. Six guide pins IZI are carried by the plate I29 and project within the sleeve H8- These pins enter holes I22 formed in an inner sleeve I23, thereby preventing the latter from rotating but permitting axial adjustment thereof. The sleeve I23 is formed with an external left hand thread. "Between the sleeves I It and I22 there is an intermediate sleeve I25 which is internally threaded to engage the left hand threads of sleeve I23 and is also formed externally with a short thread I26 adapted to engage the right hand thread of the outer sleeve II8.' Thus, if the intermediate sleeve is turned clockwise, as viewed in Fig, 9, it will be retracted or fed toward the right, as viewed in Fig. 6, and v at the same time the inner sleeve will also ,I be

retracted to a greater extent. 1

A hand wheel I28 is provided to rotate the intermediate sleeve. This wheelis mounted to turn on a projecting end of the outer sleeve I land is held against axial displacement by aretaining ring I30, secured to the adjacent end of the sleeve H8 and engaging a shoulder on the outer side of the wheel. An outer ring I32 is secured by screws I33 (Fig. 9) to the exposed face of. thereel and has projections I34 which cooperate with keyways I35 in the intermediate sleeve I25. The inner sleeve carries a short chuck shaft I36 mounted in the spiders the latching chuck is retracted by turning handle I28 clockwise. as viewed in Fig, 9.

One end of the roll is mounted on the chuck H5, and then the nose MI, of the other chuck is pro- J'ected into engagement with the opposite end of the core of the roll by turning the hand wheel counterclockwise, as viewed in Fig. 9. It will be observed that the chuck nose I4I may be very quickly retracted and projected because of the multiplying movement provided by the interthreaded sleeves, and also that such adjustment is obtained with mechanism that is very compact and, collapsible to a very small longitudinal dimension. A slight adjustment of each roll'with respect to the spiders is obtained by operating the hand wheels I I5 and I28 to adjust the chucks" I I5 and II'I. i

If it be desired to shift the rolls IM on the reel shaft so as to adjust for side register, a switch I32. which may be conveniently located on the-pedestal I6, is operated to control the motor 65. As stated above, the motor-is reversible, and the switch may be operated not only to start the motor'but also to control its direction of rotation. As long as the shifter control handle 39 remains in its normal position both of the screws 23 and 26 will be driven simultaneously by the motor 65 and the spiders will be adjusted in unison along the reel shaft. In order to adjust the reel for rolls of different width, such, for'instance, as half web rolls, one'or other of the spidersmust be adjusted to vary the spacing therebetween. If, or instance, it be desired to adjust spider 33 the handle 39 isjturned to the position 391), in Fig. '7, thereby pulling the shifter rod 25 and declutching the screw 23 from its driving gear 98. While holdingt-he handle 39 in the position 39b the operator then starts the motor in desired direction by means of a reversing switch I42. causes screw 24 to feed spider 33 along the shaft 2| while the screw 23 and spider 32 remain at rest. If the handle 39 is swung to the position. 39a the shifter rod 25 will be pushed endwise and screw 24 will be declutched from its driving gear 99 so that spider 33 will remain at rest while the screw 23 adjusts the position. of spider 32. As soon the handle 39 is released it swings automatically to normal position and is latched automatically in such position. v I

It will be observed that the mechanism just de-' scribed provides convenientmeans for effecting adjustment of the spiders individually or in unison and of controlling the direction of suchadjustment, such means being all under control of a station at one end of the reel.

While we have described a preferred embodiment of our invention it will be understood that this is merely illustrative and not limitative of our invention and that we reserve the right to make-various changes in form, construction and arrangement of parts without departing from the spirit and scope of our claims.
